    Hello Raghunath,

    Your boot issue is caused probably by the HDMI or DSS (display) drivers in your system.

    My suggestion is disabling HDMI and DSS and try to boot without those modules.

    Also, you can check and following driver - https://android.googlesource.com/kernel/omap/+/android-omap-steelhead-3.0-ics-aah/drivers/video/omap2/hdcp/hdcp_lib.c

    Hello Raghunath,

     I think that it is needed to apply some modifications in your .config file. GLP1.6.8/kernel-ubuntu/ .config

    I suggest following:

    Change these settings in your .config file

    # CONFIG_USB_MON is not set  -->   CONFIG_USB_MON=y

    CONFIG_USB_EHCI_HCD=m     -->   CONFIG_USB_EHCI_HCD=y

    # CONFIG_USB_WDM is not set  -->  CONFIG_USB_WDM=y

    # CONFIG_NOP_USB_XCEIV is not set  -->  CONFIG_NOP_USB_XCEIV=m


    After that, make menuconfig and enable:

      USB Peripheral Controller (Inventra HDRC USB Peripheral (TI, ADI, ...))  --->
  < *>   GPIO based peripheral-only VBUS sensing 'transceiver'
  [ *]   Generic ULPI Transceiver Driver  

    If the proposed steps don't work, try to enable USB driver by insmod command. 

    Best regards,
    Yanko
